To be precise, the previous comment was about whether he achieved “immortality”, not a personal sense of satisfaction in his contributions. It is gratifying to know he achieved the deep peace of believing he had been “successful”, and by that I assume you mean he achieved the important personal objectives he had set for himself. In the formal sense, no one’s personal contributions ever confer immortality (heat death of the universe) and, paradoxically (as is true for all great truths), everyone’s contributions always confer immortality (albeit anonymously). Depending on how you looks at it. The way I look at it, it’s a silly metric the monkey mind makes up to distract the actual immortal soul from experiencing a full life.
